Hard to tell what is going on. The leaves look great. Is the soil too moist or too dry? Maybe a light spritz of foiliar spray with some dilute fertilizer will help. Also keep the soil lightly damp, and make sure they are kept around 70-80 degrees F at this stage.

The first possibility is that this is way clivia grows. New clivia grows very slowly. For the first year, usually, it will have only two leaves.

The second possibility is that the temperature is too high for germination. In that situation, although the seed germinated quicker than usual, but that is a false germination and won't have true leaves come out.

Thanks for the information on the clivias. Unfortunately :(, I had them out on the back porch and either a chipmunk and/or squirrel got in the pots and destroyed both plants. The one looks like it still has roots but the other one doesn't. Both little stubs that are left have turned brown. I'm hoping that they will come back but so far nothing but I will keep the pots for a while longer.
